@p8 Awesome, I guess we need to land it in gemfile: ['rails_5_2', 'rails_6_0', 'rails_6_1', 'rails_7_0', 'rails_7_1'] too, in the darned CI workflow YAML.

Ah, right, some limits on Ruby/Rails versions for exclude/include

Because railties >= 7.2.0.beta1 depends on Ruby >= 3.1.0
  and rails_7_2.gemfile depends on railties ~> 7.2.1,
  Ruby >= 3.1.0 is required.
So, because current Ruby version is = 3.0.7,
  version solving has failed.

Thanks for chasing this!

@olleolleolle I've added Ruby 3.3 to the matrix as well.

Thanks for bringing this to my attention. Per the comments I need to do a bit of cleanup here. I'll get this done soon because it can just go in a patch release with some minor tidies I'll do in the codebase proper
